Morphological asymmetry in the greater lizardfish Saurida tumbil (Bloch, 1795) collected from the marine waters of Iraq

Abstract Asymmetrical variations in six bilateral morphological characters of 75 specimens of Saurida tumbil obtained from the marine waters of Iraq were assessed. The level of asymmetry in the snout length was highest among the morphological traits examined. Variations in asymmetry in S. tumbil increased with size. These variations are possibly due to chemical contaminants.
